3 out of 5 eggsTL;DR: noise:airflow better on paper than in practice

This review is from: bgears b-PWM 120 Black 120mm PWM technology mini 4 pin 4 wire 2 ball bearing high speed high performance 15 blades Case Fan

Pros: Bought two at another site. These are advertised as moving 110CFM and 37.3 dB at max speed. For reference, 37 dB is slightly quieter than ambient noise at a library or a refrigerator humming.

My temps are no higher than they were before I installed these.

Cons: Unfortunately, while running at similar RPMs to my other fans these produce far, far more noise - even while idling - at temps that are identical to my previous Scythe Slip Streams rated ~75 CFM.

In fact, when these spin up to high RPMs it's my opinion they actually FAR exceed the rated 37.3 dB. If I had to guess, I'd say two fans at max speed produce noise similar to using a hairdryer or hand-held vacuum cleaner ~65 dB. Iphone app maintained over 70dB at max load sitting on my desk fwiw, with ambient noise ~50dB - though I don't know how accurate the app truly is.

I have these in an airflow-and-wiring-optimized 21" tower, in addition to a Thermaltake LED fan and a Rosewill (both 120mm), and the Bgears fans overpower everything else in the case (and the room) in terms of noise. In fact, I'll probably switch to gaming and listening to music with headphones, whereas I never used to do so on account of fan noise.

There are other fans which will yield similar temps while making less noise.

Other Thoughts: I'm not displeased with the fans' performance, and I'm not opposed to the noise of a lot of air being moved (I've owned high-airflow fans before), but I did expect some temp improvement for the noise increase. Next time I'll likely get more Scythe fans and just replace them as they die (every year or two).

2 out of 5 eggsDissappoointed

This review is from: bgears b-PWM 120 Black 120mm PWM technology mini 4 pin 4 wire 2 ball bearing high speed high performance 15 blades Case Fan

Pros: Cheap, 4-pin variable speed works well

Cons: Noisy

Other Thoughts: I bought three of these to cool my white box virtualization server and keep noise to a minimum in my office. When the CPU is idling, two out of the three fans make noise. One whines/grates, and the second one occasionally makes a clicking sound. This only happens at low speed -- at high speed they sound like an attic fan.

I guess should have bought Noctua.

5 out of 5 eggsBetter than the new 120mm Nocuta-IndustrialPPC Fans

This review is from: bgears b-PWM 120 Black 120mm PWM technology mini 4 pin 4 wire 2 ball bearing high speed high performance 15 blades Case Fan

Pros: Mostly quiet, sitting at 60% in a silent room when computer is cold and when it kicks to 100% you hear airflow noise not motor noise so you really can phase it out with or without headphones. Also, it pushes MAD amounts of air. I have only one for an exhaust but man can you count on it to get the heat out, it really is impressive.

Cons: None

Other Thoughts: Their fans are pretty much silent even at full blast when their exhausting air vs in-taking air, they make a bit of noise in-taking but it's definitely worth it, keeps my FX-8350 OC'ed at 4.7 ghz, it sits right next to it and keeps the heat away from everything else very well.
Then again I am using a Noctua NH-U14S but still, amazing performance.

Also, the reason for the title of this review is I converted Nocuta's new IndustrialPPC fans cubic meters to cubic feet and their new 120mm fans are performing airflow wise the same as this one but, believe it or not, the Noctua's actually get louder than this at max speed, so if your looking at the new 120's, stop and get this. Oh and their new fans will be more than likely be around 40-50$ a piece, these are 17$.

5 out of 5 eggsNice fan

This review is from: bgears b-PWM 120 Black 120mm PWM technology mini 4 pin 4 wire 2 ball bearing high speed high performance 15 blades Case Fan

Pros: Almost always wiser quite, but if things get hot it can crank up and push a lot of air.

Cons: The pwer stub cable a little flimsy, but you really want to plug into the mobo to get the PWM to work.

5 out of 5 eggsTHESE THINGS BLOW AIR

This review is from: bgears b-PWM 120 Black 120mm PWM technology mini 4 pin 4 wire 2 ball bearing high speed high performance 15 blades Case Fan

Pros: BLOW MAD AIR
QUIET
QUALITY

Cons: can be loud at full blast, but they are cooling your cpu like a boss, so its not really a con

Other Thoughts: I got these fans for my xigmatek dark knight 2 cooler, and let me tell you, when on PWM, they are silent. They are even silent when playing games. I couldnt get over how much air they pushed too, oh man.

Once you start pushing the overclock, these motha's turn up and deliver. THey get loud, but they pump 110cfm, and can you ever tell. My 7850k @ 4400mhz and 1000mhz gpu never went above 55 degrees. Im fully amazed. I would buy these again.

Get them on sale though, dont pay full price...
